Found a couple of videos in youtube which are quite useful and very enlightening in knowing more about SuJu (although I guess seasoned fans would already know everything that is shown in the clips).
The link below is a "guide" about Leeteuk but you can view the "guides" about the other guys via the list of other videos from that same user. Some of the things can be quite touching while some are rather funny.
I think they were quite well done in my opinion =)
Enjoy!
